how many ways can velocity change
Answers
Answer:
An object can change velocity in a number of ways: it can slow down, it can speed up, or it can change direction. A change in speed, or a change in direction, or a change in both speed and direction means that the object has a change in velocity.

Explanation:
The easiest way to understand how a force alters an object's velocity is to imagine that force acting in the same direction as the velocity. For example, the jet engines on an airplane provide a force that acts in the direction of the airplane's motion, giving it a positive acceleration and making it go faster. Air friction, on the other hand, directly opposes the airplane's motion and decelerates it; if the engines stop working, the airplane will fall out of the sky. But when the force of the engine and the upward thrust of air pressure on the aerodynamically designed wings balance the force of friction and other decelerating forces, including gravity, the airplane flies at a constant velocity toward its destination.
